Wakeonlan install12/31/2023 It’s important to note that this must be the absolute path to ethtool because services don’t do relative paths. Now you need to populate your wol.service file with all it needs to run as a service:ĮxecStart provides the command to run. I use vim for all my terminal based editing so I run this command: sudo vim wol.service to create and begin editing my service file. So, navigate to: /etc/systemd/system and create a new file here called wol.service – you could be more descriptive but I prefer short filenames, I know what wol means here. On Ubuntu 18.04, you need to create a systemd service as opposed to enabling, creating and/or modifying rc.local as you would’ve done on previous versions. The problem is, this solution isn’t persistent between shutdowns so once the machine is powered down and then booted up again, the network interface configuration is lost. You may also see this command written like so: The g denotes that it should listen for magic packets. This tells ethtool to tell the network card to listen out for magic packets. Now we want to run ethtool, replacing INTERFACE with the interface name you retrieved from the previous command: Ubuntu has been transitioning to systemd since version 15.04 and part of that transition is the implementation of Predictable Network Interface Naming and so you might just find that your network interface name is something along the lines of enp0s15 Its worth noting here that all the guides I found say that “your network interface is most likely eth0”. Run the command to get the name of your network interface: Ubuntu Server 18.04 LTS already has this installed. Create a service to re-run this command each on each boot, because it does not persist.Use ethtool to tell network interface to listen for magic packets.Get network interface name with ifconfig.The steps for preparing Ubuntu for WoL are as follows: If you’re unaware, generally speaking, when an Operating System shuts down it also powers down the network adapter. Enabling wake-on-lan varies from motherboard to motherboard, depending on the manufacturer and the bios firmware installed, so if you need help enabling wake-on-lan for your particular motherboard, you should search “enable wake on lan for ”. So, I configure the bios to listen for those magic packets and locate a tutorial to enable Ubuntu to cooperate. The motherboard supports it, awesome, why not. So, I need to be able to turn it on from my laptops. That coupled with the fact that it’s next to my bed and when night sets in, it sounds like an engine next to my face. I’m not going to go to where my server is located and turn it on every time I need to access it, no sir! Nor am I going to leave it on permanently, leeching my hard earned electricity from under my nose. That, and ease of data management with PMA. Of course, there’s the whole LAMP stack on there just for shigs, though. So, long story short, I re-purposed my linux desktop pc from its semi-neglected state to something more useful. You can add your code to VCS but including a database full of test data isn’t my idea of a fun time. Local dev with databases involved isn’t very friendly across multiple machines. When I work from home, which is almost always, I often find myself working on various devices (MacBook, Windows laptop, Windows desktop) and lately I’ve been working on a heavily database oriented project. It was written for Ubuntu Server 18.04 LTS, however, the content also applies to Ubuntu Server 20.04 LTS and Ubuntu Server 22.04 LTS. I originally wrote this post around 2018 for an old blog of the same name under a different domain.
